According to the SRD, a Magical Beast's attack bonus is equal to its hit dice. And since a Familiar is a Magical Beast, its attack bonus should also be equal to its hit dice. And according to the Player's Handbook, a Familiar's hit dice is equal to its master's. So a Familiar should have a base attack bonus equal to a fighter's of the same level as its master, correct?

I ask because the NPC sorceror on page 124 of the Dungeon Master's Guide has a Tiny Viper Snake Familiar. Its Base Atk is +0. But its kobold sorceror master is level 5, and so the Familiar should have a Base Atk of +5. Note that the Familiar is also listed as having 1 HD, but it should have (5d4+3)/2. Was this a mistake or am I misinterpreting the rules somehow?

This makes a huge difference when deciding whether or not to use a familiar to deliver touch spells. If its attack bonus is equal to a fighter's, it's well worth it to have it deliver touch spells, even though you're putting it at risk. If not, it's better off sitting safely in your pocket.

Directly from the SRD:

A familiar is a normal animal that gains new powers and becomes a magical beast when summoned to service by a sorcerer or wizard. It retains the appearance, Hit Dice, base attack bonus, base save bonuses, skills, and feats of the normal animal it once was, but it is treated as a magical beast instead of an animal for the purpose of any effect that depends on its type.

Clearer?

The part from the SRD that was confusing me was:

Hit Dice: For the purpose of effects related to number of Hit Dice, use the master’s character level or the familiar’s normal HD total, whichever is higher.

Which seemed like a contradiction to the passage you quoted.

But now I'm guessing the key word is "effect", as in the effect from spells or what not, i.e. a 5th level Wizard's familiar can not be effected by a Sleep spell.

Thanks for the help.

page 52 of the phb under attakcs says they use masters bab from all classes. Under 15th level sorc for the familiar it says 15 hd, but still +0 bab. I would guess it's a mistake
